Question

Q-What is the number of water molecules contained in a drop of water weighing 0.6 gm?
by the way thanks for answering....​

Answer 1

Answer:

Explanation:

No. of molecules = given mass in gram/molecular weight × N•

Here ;

● Molecular weight of water(H2O) =

(1×2) + (16×1)

= 18 g

● Given mass = 0.06 g

● N• = 6.023 × 10^23

No. of water molecules = (0.06/18) × 6.023 × 10^23

= 1/200 × 6.023×10^23

= 3.011 × 10^21 molecules.
